344 REPORI—1890. 
Boulders from Rawtenstall.—By the kindness of Mr. Charles Bucknill, 
Mr. J. W. Gray and Mr. P. F. Kendall are enabled to record the 
following boulders from the immediate neighbourhood of Rawtenstall. 
The determinations were made from specimens submitted by Mr. 
Bucknill. 
Borrowdale ash, 2; Borrowdale lava, 7; Borrowdale amygdaloidal 
andesite, 2; volcanic rocks, source undetermined, 2 ; Buttermere ‘syenite’ 
(granophyre), 2; granites, source undetermined, 5; Criffel granite, 1; 
Loch Doon granite, 2; Eskdale granite, 10; Rig o’ Burnfoot granite, 1 ; 
granite with much muscovite, source undetermined, 1; vein quartz (like 
that from the Borrowdale series), 5; vein quartz with ochreous sand- 
stone, 1; mountain limestone chert, 1; mountain limestone, 3; red sand- 
stone, 2; hematite (fresh), 1; total 48. 
Mr. J. Horsfall (a member of the Rochdale Literary and Scientific 
Society) describes a boulder in Wardle Parish, Buckley Pasture, Roch- 
dale, just behind the college at Clough Bottom, a little to the N.W. 
Size, 10 ft. x 5 ft. x 4 ft. 6in.; angular; longest axis E.to W. Itis 
composed of a sandstone different from the adjoining rock, but a similar 
rock occurs on Rushy Hill about half a mile W. It is about 600 ft. 
above the sea; is isolated, and rests on shale. 
A group of erratics is reported by the same observer as occurring 
in Spotland Parish, Nick-o’-the-Bank Farm, about 200 yards below the 
culvert in the brook at the lower end of Ferndale Wood. It has been 
exposed by the stream, which has cut a passage through it. The largest 
boulder is 35 ft. x 2 ft. x 1 ft. 6 in.; others vary in size from this down 
to a foot in diameter, and there are hundreds of smaller dimensions. 
They are much rounded, except.the largest, which is subangular. There 
are distinct striations on one of the boulders, which is partly imbedded 
in the soil by the side of the brook. The striations, seven or eight in 
number, run along the whole Jength of the boulder (which is 2 ft. long), 
and are in the direction of its longest axis. 
This group consists of andesites, &c., from the Lake district, with a few 
specimens of Criffel granite; with angular and rounded sandstones and 
shales intermixed. It extends cver an area of 80 or 100 yards, and is 
about 800 ft. above the sea-level. 
The following group occurs in Cheshire at the localities indicated. 
A. Greave Fold, Werneth Low, near Romiley. B. Summit of 
Werneth Low, Cheshire. The figures denote the number of boulders 
found. 
Eskdale granite, A 1, B 1; Buttermere ‘syenite,’ A 1; Borrowdale 
andesite, A 1, B 6; Borrowdale agglomerate, A 3; Borrowdale rhyolite, 
B 1; Borrowdale porphyrite, A 1; Silurian grit, A 4, B 1; Coal Measure 
sandstone, A 2; quartzite, B 1; quartzite pebble from Bunter, B 1. 
Close to the highest point on Werneth Low, 821 ft. above Ordnance 
datum, is a deposit of boulder clay with scratched stones.

Kendall, F.G.S., for the following important ‘ Notes on some Erratics at
